What is the difference between thermal conductive silicone and glass glue? How to distinguish thermal conductive silicone from glass glue?

In real life, you often hear people around you talk about thermal conductive silicone, glass glue and many other glues, which can scare a lot of people at once, and many people confuse them; glass glue and thermal conductive silicone are somewhat similar, but they are used in occasions completely different. If the distinction is not made clearly, the pasted substrate may fall off. However, how to distinguish thermal conductive silica gel from glass glue may trouble many friends. CoolThermo thermal conductive silica gel is here to introduce the method of distinguishing thermal conductive silica gel from glass glue.

Features of thermally conductive silicone

Thermally conductive silicone rubber can avoid the risk of short circuits. It will not solidify or conduct electricity. It is a high-end thermally conductive compound. Thermally conductive adhesive sealing silicone rubber is a one-component, thermally conductive, room temperature curing silicone adhesive sealant.

Thermally conductive silicone is cured by cross-linking caused by moisture in the air, thereby converting it into a high-performance elastomer. It has excellent anti-cold and heat alternating performance, anti-aging performance and electrical insulation performance. And has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical resistance properties. Can be used continuously at -60~280°C and maintain performance. Non-swelling and good adhesion to most metallic and non-metallic materials.

Thermally conductive silica gel has good high thermal conductivity, thermal conductivity, electrical insulation, and its use temperature also has its selectivity, stability, low consistency and good construction performance; the thermal conductivity of thermally conductive silica gel is relative, although in flexible In the material, its thermal conductivity is better, generally in the range of 0.6-1.5W/(m·K), and a few performances may be higher, but not more than 2W/(m·K).

Thermally conductive silica gel itself is not a good conductor of heat. The function of thermally conductive silica gel is to fill the gap between the heat source and the radiator. Therefore, the thinner the thermal conductive silicon is used, the better, which is much better than the silicone sheet.

Thermally conductive silica gel can be widely applied to various electronic products, the contact surface between the heating element and the heat dissipation facility in the electrical equipment, as a heat transfer medium and has the properties of moisture-proof, dust-proof, corrosion-proof and shock-proof. It is suitable for surface coating or overall potting of various electrical appliances and devices. This type of silicon material provides excellent thermal conductivity for electronic components that generate heat.

Characteristics of glass glue

Glass glue is a common household adhesive composed of sodium silicate and acetic acid and organic silicone. Sodium silicate is easily soluble in water and is viscous. It is called water glass in the south and Paohua alkali in the north.

Glass glue is the most common and also used in our daily life; glass glue is a material for bonding and sealing various glass and other substrates; it is mainly divided into two categories: silicone glue and polyurethane glue (PU glue). ). One of the most common is silicone sealant, often referred to as glass glue.

Silicone sealants are divided into two types: acidic and neutral. Acidic silicone sealants have stronger adhesion than neutral ones; , Electronic sealant, etc.

The sealant is used to fill the configuration gap to play a sealing role. It will deform with the shape of the sealing surface and is not easy to flow. Insulation, etc.

General sealants can be divided into three categories: elastic sealants, liquid sealing gaskets and sealing putty.

Glass glue is a general term. Adhesives used to bond glass can be called glass glue. Silicone glue and polyurethane glue belong to glass glue.

Sealant is distinguished in terms of performance. The single-finger function is an adhesive for sealing. Weather-resistant adhesive, silicone structural adhesive and polyurethane adhesive all have a sealing effect, but they have other important functions, such as high bonding strength and good weather resistance.

For the introduction of the method of distinguishing thermal conductive silica gel and glass adhesive, Nuofeng thermal conductive silica gel has introduced so much, and finally summarizes a little. conditions, use the correct adhesive.
